Clip board for holding writing paper



July 28, 1953' J. SCHWER CLIP BOARD FOR HOLDING WRITING PAPER Filed June24, 1952 INVENTOR. JoH/v \SCHWE-R. BYQ Z a his raeA/mr Patented July 28,1953 -UNITED STATES vPATENT OFFICE 2 Claims.

My invention relates to clip boards and the like for holding writingpaper, scratch pads, etc., and has for its object the provision of aholder that can conveniently have one corner inserted into thetriangular pockets usually employed on desk blotter holders forreceiving the corners of desk blotters.

The invention is particularly useful for holding scratch sheets or thelike against displacement while writing thereon, when the users otherhand is holding a telephone receiver.

As shown in the accompanying drawing,

Figure 1 is a fragmentary plan view of a desk blotter holder showing themanner in which my invention may be employed therewith;

Fig. 2 is an edge elevational view of the structure of Fig. 1;

Fig. 3 is a view taken on the line III-III of Fig. 1, and

Fig. 4 is a plan view of the base board or plate portion of myinvention.

The holder can conveniently be made of sheet metal or a plastic, andcomprises a base plate 6 having lips I at its edges and bendabledownwardly for engagement with the board portion 8 of a desk blotterholder, to prevent the clip board from shifting on the blotter holderwhen the nose portion 9 of the plate 6 is inserted in one of thetriangular pockets formed by the usual leather-like pieces It used atthe corners of the holder 8 and into which the corners of the blottersare inserted.

Ears I2 are struck up from the plate -6 to serve as bearings for a shaftI3 that also extends through ears I4 struck downwardly from a clampingplate I5. A coil spring I6 surrounds the shaft I3 and has one free endthereof abutting the upper surface of the plate 6, and at its other end,tension against the underface of the clamping plate I5, to thereby exerttorsional stress to hold the down-turned edge of the clamping plate ingripping engagement with a sheet of paper or pad II. If the plate '6 ismade of metal, it may suitably have a sheet I8 of cloth glued to theundersurface thereof.

The clamping plate I5 has a lever-like extension I9 by which it can berocked against the tension of the spring I6 to lift the forward or jawportion of the plate from the sheets II.

It will be seen that by reason of the triangular pocket I and the lips'I, the plate *6 is held in all directions against shifting. Also, it

I claim as my invention:

1. A clip board comprising a base plate, a clamping plate pivotallymounted thereon, on a diagonal axis adjacent to a corner of the baseplate, a spring yieldably urging the inner edge of the clamping plateinto grippingjengagement with sheets that overlie an inner portion ofthe base plate, and down-turned lips at the marginal edges of the plate,set inwardly from the said corner, the said outer corner being adaptedto be slid into a triangular pocket in a desk blotter holder and thelips engageable with the adjacent edges of said holder, at pointsremoved from the triangular pocket.

2. A clip board comprising a base plate having ears struck upwardlytherefrom along a diagonal line set inwardly from a corner of the plate,a shaft supported by said ears, with its axis along said diagonal line,a clamping plate supported by said shaft, a spring; engageable with thebase plate and the clamping plate and biased in a direction to efiectgripping engagement between the inner edge of the clamping plate and theadjacent underlying area of the base plate, the said corner beingadapted to be slid into a triangular pocket of adesk blotter holder andthe said shaft being set inwardly from the diagonal edge of said pocket,so that the outer portion of the clamping plate will be above the pocketcan serve as a leverlike extension for opening the inner edge of theclamping plate relative to the base plate.
